◎Excellent sealing performance, using metal bellows as the key sealing component, with its lower end welded to the valve stem assembly and its upper end connected to the
Plate welding forms a metal barrier to prevent fluid medium leakage and achieve zero
leakage of the valve stem
◎The main components such as the valve body are made of forged steel with high structural strength, resulting in a more uniform structure, better density and strength integrity, and dimensional errors small, with better performance compared to castings, able to withstand higher pressure and temperature
◎ Easy and reliable operation
The dual guarantee of long service life with corrugated pipe sealing and packing sealing
reduces the risk of leakage and lowers the frequency of maintenance; Valve body and
◎The minimum wall thickness design of the valve cover meets the requirements of relevant standards, ensuring the strength and rigidity of the valve under harsh working conditions such as high temperature and high pressur

Forged steel corrugated pipe globe valves are widely used in pipelines of industries such as power, petrochemicals, papermaking, metallurgy, aerospace, etc., as a medium for connecting or cutting off. For example, in the oil and gas industry, it can be used for cutting off or regulating pipelines; In the chemical industry, transport control systems suitable for various chemical media; In the power system, it can be applied to the cooling water system, steam system, etc. of power plants
The quality of forged steel parts is higher than that of cast steel parts, and they can withstand large impact forces. Their plasticity, toughness, and other mechanical properties are higher than those of cast steel parts. The diameter of forged steel stop valves is generally not more than DN80, and most of them are reduced-diameter designs. Compared with cast steel stop valves of the same diameter, the flow rate is slightly lower, but the pressure and temperature range they can withstand are higher than those of cast steel valves, and their sealing performance is much better than that of cast steel stop valves, and their service life is longer. Like other stop valves, they are subject to the restrictions of the flow direction of the medium. Forged steel stop valves can be divided into straight-through stop valves (type stop valves) and direct-flow stop valves (Y-type stop valves) according to installation positions.
The quality of forged steel parts is higher than that of cast steel parts, and they can withstand the impact of beatings. The plasticity, toughness, and other mechanical properties are higher than those of cast steel parts. The diameter of cast steel gate valves is generally not more than DN80, and most of them are reduced-diameter designs. Compared with cast steel gate valves of the same diameter, the flow rate is slightly lower, but the pressure and temperature range they can withstand are higher than those of cast steel valves, and the sealing performance is much better than that of cast steel gate valves, and the service life is longer. The flow direction of the medium is not restricted like other gate valves.
